GEARING.

SPECIFICATION forming part of Letters Patent No. 244,264, dated July 12, 1881.

Application filed Juno 16,1i381. (NomodcL) To all whom it may concern Be it known that I, THOMAS T. LEAGOX, of Imogene, in the county of Fremont and State of Iowa, have invented certain new and useful Improvements in Gearing for Mills and other Machinery; andI do hereby declare the following to be a full, clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to an improvement in gearing for mills and other machinery; and it consists in attaching to the steam-engine, water-wheel, or other motive power a series of wheels which are so proportioned that each one is a multiple of the one with which it meshes, and applying the power to the shaft of a pinion which meshes with a large driving-wheel, whereby the necessary velocity is obtained without the usual great loss of friction consequent upon the usual manner of applying the motive power to the wheels, as will be more fully described hereinafter.

The object of my invention is to provide a gearing or system of wheels which is placed between the engine, water-wheel, or othermotive power and the machine or gearing which is to be driven, the combination of wheels being so geared as to give the necessary rate of speed to themachine which is being driven without running the motive power any faster than usual, and yet not lose so great a percentage of power as is usually done where the power is applied to the multiplying-gear in the usual manner.

Figure 1 is a plan view of my invention, and Fig.2 is an end view of the same.

Heretofore, where a multiplying-gear has been used for increasing the speed of the machine that is being driven, the power has always been applied directly to the end of the shaft A, upon which the large gear-wheel B is placed. The result of attaching the driving-power to this shaft has always been that a much greater amount of power was required to run this combination of wheels,which gives the necessary speed to the machine which was to be driven, so that what was gained in speed was lost inpower. In order to use this combipinion D, which pinion D meshes with and drives the large wheel B. The wheelB being made to revolve by this pinion D, the shaft A, which has a second large wheel, E, secured to it, is set in motion. This second wheel E should be about one-half the size of the wheel B. This wheel E, in turn, meshes with the pinion F on the shaft G. On this shaft G is placed a second larger wheel, H, which meshes with the pinion I on the shaft J, to which the mill-gearing or other machinery to be driven is geared.

All of the above-described wheels bear a certain relation to each other in size, and the pinions are made one-fourth of the size of the larger wheels with which they mesh. By this relative arrangement of sizes a much better result is obtained and a much more uniform and perfect motion is given to the machine which is being driven than where the wheels bear no special relation to each other in size. While the engine is in motion the whole strain of the driving-power 'comes upon the pinion D and the large driving-wheel B, while the resistance of the machinery which is being driven comes upon all that part of the combination of wheels'which is placed between the second large driving-wheel and the shaft which is attached directly to the machine.

So great is the-friction of the combination of wheels that where the motive power is applied to the shaft A it takes five pounds to engine or a water-wheel, so great is the saving of power that the engine or water-wheel can be run with just one-half its usual force, and will accomplish the same result as when run- 5 ning at full capacity if the power is applied directly to shaft A.

Having thus described my invention, I claim- The multiplying-gear, constructed as de- 10 scribed and adapted for driving a mill or other machinery, the motive power being applied through the small wheel D to the large one, B, and transmitted to the other wheels, in the manner and for the purpose described.

In testimony whereof I affix my signature 15 in presence of two witnesses.
